Thanks for the heads-up.  Looks like a new toy :)

How are you finding Dacentec with the improved network blend?  Were you a client before they added their new upstream?

Congratulations.  drmike where did you place QPS? 

It doesn't matter if it is one month, two months or a quarter.  You have no substantial historical data to base expansion plans on.  I said way way back in this thread that your bubble was going to burst.  This was before you made it very clear you have zero business acumen.  I think posting...

No.

Well even with trying some things I've seen in the past to cause this (such as switching the GEN3 PCIE slots to GEN2 and adjusting PCIE timings) I'm still unable to get anything better.  I've let the company know and they will be looking into it Monday.  I'll update this thread with any solution...

Thanks.  At least I've got something to go back to the provider with.  

Well I was expecting around 600-650 from this setup.  The ES.3 are superior drives and obviously the 9271 is a superior card so that makes sense with your result.  Did you do anything special to the filesystem beyond general alignment and read-ahead?

They are saying that sub 300 is normal; however based on my experience with other cards and different configs it can't be the case.  I can push around the 300 mark on a four disk array on a lesser card.  This should show a linear increase in performance (doubled), which is why I was puzzled.  I...

Ahh, total typo there, thanks for pointing it out.  It is indeed a 9261.   dd if=/dev/zero of=test bs=64k count=7k conv=fdatasync; unlink test 7168+0 records in 7168+0 records out 469762048 bytes (470 MB) copied, 1.34486 s, 349 MB/s

This was exactly the post I had in my head but couldn't be bothered to type.  Thanks

Which is exactly why the results were confusing as I can push just under 300mb/s on a four disk H/W raid 10 array or just under 250mb/s on a four disk S/W raid 10 array. I know the 9261 is not up there with the likes of a 9271; however I certainly wouldn't consider a 9261 a low end raid card...

I was referring to Disk cache enabled.  Card has 512mb cache.  9261 is AFAIK pretty much the same as 9260 except a different board layout.

Yes write-back and cache enabled. 

Right around 300 MB/s

Granted, I've never run an 8 disk array before (generally four or twelve).  If anyone has an experience of an 8 disk raid 10 array, what kind of speeds would you expect to see from the misguided but widely accepted DD test? Spec of the array: 8 x WD RE4 2TB LSI 9621-8i I would have expected...

Every post you write just makes me cringe even more.  I wish you the best of luck. 

You can't pay for infrastructure, eight techs and a WHT pinned on $5,000/mo

Right.  I won't bother wasting my time typing more.

With my recent experiences I'd strongly suggest reconsidering your Dallas location.
